PVB and SGP laminated glass are two common safety glass materials, and their main differences are as follows:
1. Sandwich material
PVB sandwich material is a polyvinyl alcohol ester material, while SGP sandwich material is a polyurethane material.
2. Material performance
PVB interlayer material has excellent anti-ultraviolet and anti-aging functions, and is more widely used in outdoor applications. SGP interlayer materials are more suitable for glass products that require higher strength and higher quality requirements, such as glass curtain walls of high-rise buildings.
3. Safety
PVB laminated glass can effectively resist external shock and vibration, and also has the functions of sound absorption and heat insulation. The SGP laminated glass not only has the above advantages, but also has higher impact resistance and bending resistance.Bending Deflection = 1/4 of PVB.
4. Price
The price of PVB laminated glass is relatively low, which is suitable for general architectural glass products. The price of SGP laminated glass is relatively high, which is suitable for high-quality architectural glass products.
5. Thickness
PVB thickness is a multiple of 0.38
